METHOD OF MANUFACTURING PANEL AND PANEL MADE FROM THIS METHOD {METHODS FOR MANUFACTURING PANELS AND PANEL OBTAINED THEREBY}

This application is incorporated by reference in U.S. Patent No. 35.U.S.C 119 (e), filed December 19, 2008. Claim the benefits of 61 / 139,286.

The present invention relates to a method of manufacturing a panel and a panel obtainable through this method.

In particular, the present invention relates to a method of manufacturing a panel of a type comprising at least a substrate and an upper layer having a pattern provided on the substrate. Here, the present invention relates, for example, to furniture panels, ceiling panels, floor panels, etc., which are substantially composed of MDF or HDF (medium density or high density fiberboard) base panels or substrates and top layers formed thereon. In particular, it relates to a method comprising at least one layer of material provided on the substrate, wherein at least one of the layers of material comprises a printed pattern. Preferably, it relates to a pattern obtained at least in part through printing carried out directly or indirectly on the substrate. However, the present invention applies to panels, wherein the pattern forms, for example, such a pattern on a carrier sheet, and the carrier is applied to the substrate, in this case, for example, a DPL (Direct Press Laminate) laminate panel. It is realized by another method of forming a sheet.

Such panels are for example US 1,971,067, US 3,173,804, US 3,554,827, US 3,811,915, WO 01/48333, WO 01/47724, US 2004/0026017, WO 2004/042168, EP 1 872 959, DE 197 25 829 C1 or It is widely known in DE 195 32 819 A1 and the like. From the foregoing publications, the above-described material layer may comprise one or more base layers located substantially below the printing and / or one or more finishing layers substantially spreading over the pattern. Such a finishing layer may comprise, for example, a layer of transparent or translucent synthetic material, which will form a protective layer on the pattern, with or without printing, and may also contain wear resistant particles such as, for example, aluminum oxide. It may also include. This protection layer is not excluded from the fact that, for example, a material sheet such as a paper sheet in which a synthetic material such as an amino resin is made of a material.

From the foregoing patent publications, various methods are known for providing the surface of a coated panel comprising a structure. From WO 2004/042168 a method is known for forming recesses in the substrate itself or in the base layer and in the form of a pattern in the form of a pattern on such a structured substrate. From WO 01/47725, US Pat. No. 3,811,915 and US Pat. No. 3,554,827, it is known to provide gloss-waterproof means on top of printed patterns, as a result of which the transparent varnish layer is optionally solidified to form structures in the final panel. From WO 01/48333 it is known to provide impressions comprising the aid of a mold or a pressurized cylinder in a layer of polish provided on top of the pattern. From WO 01/47724 a method of providing a transparent varnish layer selectively using inkjet on top of a pattern and forming a structure in this way is known, whereby the varnish layer only partially covers the pattern, It is known that a portion of the pattern is not protected from abrasion. From DE 197 25 829 C1 a technique is known which presses onto the protective layer which is applied on top of the pattern via a mold or pressurized cylinder or press plate. DE 197 25 829 C1 is applied in a liquid state and a protective layer comprising a thermosetting resin such as melamine is used.

With regard to flexibility and / or the structuring to be realized, the foregoing documents do not meet many of the requirements. For example, these techniques do not realize structuring in a flexible manner in response to patterns formed in printing. In addition, according to some known techniques, the pattern is not partially protected against wear or moisture permeability, for example.

Through various independent aspects, it is an object of the present invention, in particular, to provide an alternative method by which a coating panel of the type described above can be produced, and through various preferred embodiments, more flexible than what is mentioned in the prior art. And / or provide a more economical method, and may provide a solution that solves one or more problems of the prior art methods.

In order to accomplish this object, a first independent aspect of the present invention relates to a method of manufacturing a coating panel of a type comprising at least a substrate and an upper layer having a pattern provided on the substrate, wherein the method of realizing the upper layer At least two steps of a first step of providing a layer of synthetic material to the substrate and a subsequent second step of providing a relief on the surface of the layer of synthetic material, wherein the relief is a recess and / or a protrusion. Wherein the pattern is at least partially determined by one or more printings. There may be another layer of material between the substrate and the layer of synthetic material, such as a layer representing at least part of the pattern or the entire pattern.

According to this first aspect of the present invention, relief can be obtained after the corresponding portion of the synthetic material layer has already been formed. In this way, in order to form the composite material layer itself, a suitable technique for coating a flat substrate can be selected, which can greatly simplify this method and thus, unexpected inclusions such as air inclusions in the composite material layer. This risk can be limited and even prevented.

Since the pattern of relief is determined at least in part by printing, the structure or relief corresponding to the pattern can be applied more simply, smoothly, and more flexibly. For example, the technique of forming a pattern and forming one or more prints may be applied simultaneously, thereby obtaining a similar result in which the pattern and the corresponding embossed portions are formed. Preferably, digital printing techniques such as inkjet printing can be applied. Of course, printing techniques using pressurized cylinders such as offset printing or gravure printing can also be applied.

One or more print colors and / or print hues corresponding to individual portions or reliefs of the structure may remain visible on the outer surface of the final coating panel. In the case of wood structures in which there are wood holes that mimic the concave structure, the color and / or color tone of the wood holes can be formed in this way.

The first aspect may be realized in various possible ways, and four possible ways are described below.

In a first possible manner, printing located underneath the synthetic material layer is used, for example applied in a step prior to or simultaneously with the first step described above. For example, one skilled in the art can apply printing using an expanding agent, and then, according to the present invention, after applying the layer of synthetic material, the expanding agent is expanded during the second step and is provided thereon. The synthetic material layer is deformed.

During expansion, the layer of synthetic material may be flexible or already solidified in whole or in part. When using synthetic material layers that are not completely solidified, they may solidify as the structures are formed.

The start of printing expansion can be achieved, for example, by heating using an oven or radiation. Here, the expansion is limited by the mechanical mold element and in contact with the composite material layer, as a result of which a more structured shape can be obtained, in particular the circular part can be reduced or made smaller. Such mold elements may, for example, form fillets at one or more edges of the object panel.

Instead of printing with an intumescent agent, the first possible printing scheme may be performed using an inflation agent, which will partially correspond to the overall desired inflation. This embodiment only needs to appear concave on the limited surface when the entire planar structure is formed. In this case, for example, in the case of a wood structure, the wood hole may be in the form of a wood hole on the surface of the entire plane. Other embodiments herein may be in the form of joints or fillets.

In particular, it may include, for example, benzotriazole and / or tolyltriazole as antiswelling agents. Such products can reduce or prevent expansion of synthetic materials such as PVC. As the expanding agent, a product containing such PVC can be applied.

As an auxiliary way of the first possible manner, the printing for determining the structure can be located not only under the composite material layer but also under the pattern. According to this possible manner, the pattern can be structured as the pattern itself, and the depth effect can also be obtained.

As another auxiliary way of the first possible manner, an swelling agent or an anti-expansion agent may be located on and / or form part of the pattern. For example, such additives may be applied to form a patterned portion that is intended to exist as protrusions and recesses, respectively, on the surface of the coating panel. Thus, the wood texture and / or wood holes of the wood pattern can be printed with a pigment or ink containing an anti-swelling agent.

According to a second possible manner, for example, a print located above the synthetic material layer can be produced in the manner of the first step below. Such printing can be applied, for example, in the form of an additive that can form recesses on the surface of the synthetic material layer, whether before or after activation of the additive. For example, if possible, additives may be selected which can partially dissolve, corrode, heat, melt or emulsify the synthetic material layer after activation, thereby allowing the corresponding part of the rinse treatment or synthetic material layer, if possible. After another process of removal, recesses may be created in the composite material layer in the printed portion.

According to another embodiment of this second possible manner, such printing may be applied in the form of additives which can form protrusions on the surface of the synthetic material layer, whether before or after activation of the additives. For example, the printing may be in the form of already having a certain thickness and attached to the synthetic material layer, or may be in the form of a part in which the synthetic material expands or includes an additive which can prevent such expansion. . Here, this approach can be carried out in a manner somewhat similar to the first possible approach described above, with the difference that a corresponding expander or anti-expansion agent is located on top of the synthetic material layer.

According to a third possible manner of the first aspect of the present invention, such printing can be carried out in the form of forming a structure on a pressing element such as a conveying element or a roll, through which at least partially structured conveying element is produced. It is carried out to form a recess in the material layer. Preferably, the structure of this conveying element is formed inline and / or simultaneously with the step of forming a recess in the composite material layer. Preferably, it is the printed additive itself that forms the structure of the conveying element. To this end, waxes or varnishes can be used, for example, and do not exclude additives comprising zinc or tin.

According to a fourth possible manner of the first aspect of the present invention, the printing may be performed in the form of forming a mask on, in, or under the layer of synthetic material, which mask may, for example, remove material and / or Alternatively, a material deposition process allows for selective processing of the synthetic material layer, through which such masks determine the pattern of recesses and / or protrusions. Prior to the selective treatment, a selective drying treatment may be performed on the same mask or a portion of the mask. For example, using a mask, selective ultraviolet or electron beams that preserve a layer of polish or other synthetic material can be obtained in a flexible manner. After performing the treatment, the less solidified portion of the mask and the synthetic material layer is suitable, for example, by techniques such as brushing and / or aspirating the mask present with the unsolidified portion of the synthetic material layer. It may or may not be removed by a material removal technique. According to a preferred embodiment of this fourth possible manner, another embodiment of the fourth aspect of the present invention described above can be obtained. As an auxiliary possible way of this fourth possible way, a mask is obtained by forming the print on an individual foil or material web or sheet of material, which foil is preferably made substantially transparent or translucent. Such foils provided for printing can be obtained, for example, via selective blocking ultraviolet rays or electron beams, and are between the layer of synthetic material and the radiation source to be preserved. As mentioned above, this portion of the foil will be translucent or transparent so as to be transparent to the radiation used when preserving the synthetic material layer.

A method such as the third possible manner of the first aspect described above, such as forming a second independent invention aspect of the present invention, simultaneously forms a recess in the surface of the panel and / or the structure of the mechanical pressing element in-line. Formed, the structure of the pressing element may or may not be obtained through printing. Such pressing elements can be, for example, belts, cylinders or flat plates, etc., which can consist essentially of metals such as steel alloys or copper alloys, synthetic materials such as silicone or melamine resins. Instead of using printing, structures may be formed, for example, through material growth or material attachment techniques such as selective laser melting or sintering, stereolithography, coating, and the like. As another possible manner, a material removal technique can be used, preferably a layer of update material formed on the pressing element of interest, and as a result, the structure of the pressing element can be produced several times. As another possible way, each pressing element can include a mechanism that can alter the structure of the surface. This possible manner is particularly useful for widespread pressurization, such as pressing to form joins, fillets or slopes. By "simultaneously and / or inline" it is meant that the pressing elements on which each structure is formed can be embossed on the surface of the panel, at least in part, preferably at the same moment.

The second independent aspect of the invention may be defined as a method of making a coating panel of a type comprising at least a substrate and a patterned top layer formed thereon, the method comprising the steps of: forming a layer of synthetic material on at least the substrate; And embossing this composite layer using a structured mechanical pressing element, wherein the structure of the pressing element is formed simultaneously and / or inline with the embossing of the composite material. Preferably, the other structure of the pressing element is used in providing embossing to the synthetic material and is formed in the pressing element at the same time. Preferably, a mechanical pressing element in the form of a belt or web is used, for example, this pressing element performs a continuous movement along a roller such as a pressing roller. The belt and net are advantageous in that they can have a relatively wider surface than the surface of the coating panel. This can maintain a sufficiently long distance between where the structure is formed and where the other structure comes into contact with the synthetic material layer.

The embossing of the composite layer may be performed in various possible ways. According to a first possible manner, the synthetic material is provided to the panel before embossing is formed on the composite material layer. According to a second possible manner, an embossment may be provided on the synthetic material before the panel is provided with a structured synthetic material layer. Thus, for example, it is possible for the synthetic material to be provided in an already structured part of the pressing element, and it is also possible for the formed synthetic material layer to be transferred or conveyed to the panel. For example, a person skilled in the art can operate substantially through the method known from WO 2007/059967 publication. In the method of this international patent application, a layer of polish is provided to the structured material web, and then the structured synthetic material layer is moved to the panel, wherein the structured material web described above is used. According to this aspect, instead of using the structured material web described above, a structured material web is used in-line and / or simultaneously.

According to the present invention, the structures formed in-line and / or at the same time can be used many times to provide relief to the synthetic material. It is also possible, in the case of using the corresponding pressing element again, to use the structure used to form the relief of one or more panels, again forming the structure. The pressing element may also be considered for the purpose of single use.

The method comprising the features of the second aspect is advantageous in that a very large amount of embossment can be produced using the same pressing element. It is also possible to flexibly adapt the change to other predetermined structures.

According to a third independent aspect, the present invention relates to a method for producing a coating panel of a type comprising at least a substrate and a patterned top layer provided on the substrate, wherein the step of realizing the top layer comprises two steps, namely the A first step of providing a layer of synthetic material to the substrate followed by two steps of providing an embossment on the surface of the layer of synthetic material, the embossment comprising concave and / or protrusion shapes, the pattern being at least the top layer And / or features obtained in part by locally increasing and / or decreasing the size of the substrate.

"Locally" here means that the entire top layer is equally increased and / or small. This is associated with an increase and / or a small volume change in very narrow portions. In order to form the corners present in the lower position, they are provided, for example, in the form of joins, fillets or recessed varnish layers, for example at the corners, a locally small amount of volume is increased or even While a decrease occurs, an increase in volume as a whole can be observed at the surface of the top layer. According to another embodiment, it can be observed that in order to form recesses in which wood holes or other local differences are present, a locally small amount of volume is increased or decreased, while the volume of the upper layer is increased equally throughout.

According to the third aspect of the invention, relief is obtained only after the corresponding synthetic material layer is already formed. Here, in order to provide the composite material layer itself, a suitable technique for coating the planar substrate can be selected, which simplifies this method or reduces the risk of unexpected inclusions, such as air inclusions, being formed in the composite material layer. I can ease it.

In addition, the possible ways described above associated with the first aspect may be used with an swelling agent or an antiswelling agent, and may be examples of this third independent aspect. Such additives may be provided to the substrate in any manner with or without printing.

The volume increase of the third aspect can be obtained in any way. For example, it may be generated through the result of a chemical reaction, in which a gaseous substance is formed in the upper layer, and may maintain a larger volume than the active particles of the upper layer.

Preferably, the increase in volume is related to at least an increase in the volume of the composite material layer. Preferably, this synthetic material layer is located on the pattern and is formed transparent or translucent. Preferably, the composite material layer forms an upper side of the coating panel. However, regardless of the inclusion of rigid particles such as aluminum oxide particles on top of the synthetic material layer, a finish layer such as one or more varnish layers may be further included. According to the present invention, the synthetic material layer may be located under or be part of the pattern, and the layer may also exhibit a specific color tone.

According to a preferred embodiment of the third aspect, the increase or decrease in volume is carried out in a controlled manner, for example in a controlled manner in which a mold is replaced, such as a structured flat pressing plate or other structured pressing element, The structure of this pressing element relates to the opposite or approximately opposite of the reliefs formed on the surface of said at least one coating panel.

According to another preferred embodiment of the third aspect, the relief formed through the reduction or increase in volume is finished with a material removal and / or material addition technique such as laser processing or stereolithography.

According to the third aspect, an increase or decrease in volume appears at the surface of the substrate. Such an embodiment can be obtained, for example, in the form of the surface of the substrate or a material expanding on such a substrate. For example, a material may be provided that expands to wood fibers present in a layer at the surface of an MDF or HDF board. According to a variant deviating from the third aspect, the embossing need not be formed after providing the synthetic material layer. Using this inventive MDF / HDF or other wood based board, one can come up with a number of new possible ways of making structured panels. According to this variant, the coating panel can be obtained, for example, via the following steps, including several steps of execution: for example, a possible manner of locally inflating or expanding the layer of synthetic material described herein above. Locally expanding the substrate of the wood substrate and providing a pattern and a protective transparent or translucent layer.

According to a fourth independent aspect, the invention relates to a method for producing a coating panel of the type comprising at least a substrate and a patterned top layer formed on the substrate, wherein the method of forming the top layer is at least two steps, namely A first step of providing a layer of synthetic material to the substrate followed by a second step of providing an embossment on the surface of the layer of synthetic material, the embossment comprising the form of recesses and / or protrusions, the pattern being It can be obtained by providing a mask on the synthetic material layer, followed by subjecting the synthetic material layer to a material removal and / or material attachment process, wherein the mask is characterized at least in part in determining the pattern.

The use of a mask, optionally by applying and removing material to the layer of synthetic material, opens up new possibilities for embossing at the surface of the coating panel. To use the mask, a printing technique such as inkjet printing can be used, through which the features of the first aspect of the invention can be obtained, in particular the features of the fourth possible manner of this first aspect. . Preferably, as a printing technique, a similar technique is used as a form capable of forming the pattern. In this way, a mask corresponding to the pattern can be formed in a simple manner, which can be converted into an embossed form corresponding to the pattern. Preferably, the printing technique can obtain approximately the same result as the printing technique for forming the pattern, so that the embossed finally formed is as good as the pattern.

According to a fourth aspect of the invention, embossing can only be obtained after each part of the synthetic material layer has already been used. Here, in order to use the synthetic material layer itself, a suitable technique for the coated planar substrate must be selected, which simplifies this method and at the same time limits the risk of unexpected inclusions such as air inclusions formed in the composite layer. Or prevent it. However, the mask according to the above possible manner is applied in preference to the material layer.

Preferably, the mask comprises or consists of means capable of resisting material removal and / or material attachment techniques, as a result of which each technique can optionally be used in a location where the mask is not present or deviated from the opening. In the opposite case, it is also possible for each technique to be used only where the mask is present.

As the material removal technique, for example, a chemical etching technique that acts locally on the synthetic material layer may be used, and a mechanical corrosion technique such as sandblasting or shot peening may be used. As the material removal technique, at least suction treatment may be used. The latter technique is practically suitable when a mask or a portion of the mask is used to selectively preserve the composite layer, so that the portion of the composite material layer, preferably located below the mask material, is not solidified or solidified in a narrow area. Happens.

As a material attachment or material growth technique, for example, stereolithography may be used or spray techniques such as injection molding or immersion techniques may be used, preferably the material is bonded where the mask disappears or opens.

According to a fourth aspect, the mask may be removed from the synthetic material layer after the relief is formed. However, the mask remains in the final coating panel, for example making up a final embossed or final patterned portion. As a material attachment technique, the technique can be used at least where the mask is permanently bonded to the synthetic material layer. If the mask is held at least partially in the final coating panel, the color of the mask may correspond to the desired appearance of the decorative layer of the final coating panel.

According to the fourth aspect, instead of the mask being formed in the panel, the mask is formed separately, i.e., formed as an entity. For example, it is also possible for the mask to comprise individual foils or consist of individual foils, such individual foils or any other individual sheet of material, preferably made of transparent or translucent, comprising a mask portion, material removal and / or material Resistant to adhesion treatment, a synthetic material located underneath the mask portion is widely exposed to this treatment.

In particular, according to the embodiment, it is also possible to form a plurality of masks stacked on each other. Through this embodiment, the relief characteristics can be further modified. For example, this technique can be used to obtain deeper and / or three-dimensional structures. In addition, such techniques may form curved recesses and / or protrusions, and may form recesses and / or protrusions having an area / thickness ratio, an area / height ratio of less than 1 or less than 0.75, respectively.

As shown in various preferred embodiments of this fourth aspect, at least the synthetic material layer is partially preserved between the first step of applying the synthetic material layer and the second step of embossing the surface of the synthetic material layer. An intermediate step may be performed. This preservation step is preferably performed selectively and is better in that it is in a manner determined at least in part by a portion of the mask.

As mentioned above, two types of masks, a first type in which the mask portion of the mask resists the material removal and / or material adhesion treatment, and a synthetic material located underneath the mask portion are extensively exposed to these treatments. Substantially differences can occur in the second form in which the mask portion of the mask is provided to be. Preferably, the latter can carry out the preservation of the layer of synthetic material using the same mask, for example ultraviolet or electron beam, or the same mask via heat, the mask portion preferably radiating and / or subjecting the object. Or to form a screen for heating. In this way, the less solidified part can be exposed to a wide range of treatments, for example, after which the material removal treatment has to be carried out.

The material used to form the mask portion of the fourth aspect mask should be appropriately selected according to the required function. For example, waxes or paraffins can be used.

Preferably, the mask is formed inline and / or concurrently with the embossing of the synthetic material. Preferably, other mask portions of the mask are used when forming relief rather than being formed simultaneously. Preferably, when a mask is used, an independent type of entity can be made, for example a mask in the form of a belt or a web, for example continuous in that such a mask is conveyed along a roller such as a pressure cylinder. Massive movements may be preferably performed.

The present invention relates to a panel obtainable according to a method comprising the features of one or more aspects of the present invention. Here, for example, with reference to a coating panel in the form of at least a substrate and a patterned top layer formed on the substrate, the top layer comprising a transparent or translucent synthetic material layer, the composite material layer being the It is formed on top of a printed pattern, and the layer of synthetic material can be foamed or includes foamed synthetic material. It is clear that such a panel can be manufactured using the technique according to the first and / or third aspect of the present invention.

Preferably, the foamed synthetic material is selected from polyvinylchloride, polystyrene, polyethylene, polypropylene, acrylate, polyamide, polyester and the like. Preferably, the composite material layer is spread over substantially the entire printed pattern.

As the substrate of the coating panel of the present invention, a substrate preferably comprising a wood-based material such as MDF or HDF can be used.

Preferably, the coated panel is associated with a panel and a pattern associated with the printed pattern obtained by forming a print directly or indirectly on the panel.

Coating panels obtained using a method incorporating features of the present invention exhibit reliefs at their surfaces obtained using techniques in accordance with one or more embodiments described above and / or described below.

In particular according to a fifth independent aspect, the invention relates to a method for producing a coating panel of the type comprising at least a substrate and a patterned top layer formed on the substrate, the top layer being synthesized in at least two steps, ie the substrate. A first step of providing a material layer and a second step of providing an embossment on the surface of the synthetic material layer, the embossment comprising a pattern of recesses and / or protrusions, the pattern being adapted for digital printing. Is determined at least in part. According to this aspect, the second step does not necessarily have to occur after the first step, and the synthetic material layer does not necessarily have to be provided where an embossment is already formed on the substrate surface.

The printing of the first aspect and the mask of the fourth aspect can be obtained through digital technology, including, for example, printing formed through an inkjet printer. Thus, the first and / or fourth aspect may be an example of this fifth independent aspect.

In general, according to aspects of the present invention, whether or not temporary, digital technology can be used to form a mask that determines at least part of the pattern, or can be a synthetic material repellent, gloss repellent, swell or swell Also used to provide the inhibitor, the additive so applied determines at least part of the pattern.

In addition, the digital technique can be carried out by a conveying element or a mechanical pressing element, which is performed simultaneously with the manufacturing line and / or forming the relief. In this way, the embodiment of the second independent aspect described above can be obtained.

According to all aspects of the present invention, the synthetic material is preferably substantially spread over the entire surface of the substrate. In this way, reliefs or structures can be obtained on the entire surface of the structure. Preferably, the composite material layer is finally spread in the form of a coating panel over substantially the entire surface of the substrate. Thus, the material of this composite material layer is present up to the deep structure of the upper layer. In this way, an excellent protective layer for protecting the pattern can also be obtained.

As mentioned in all aspects of the present invention, the synthetic material layer is preferably associated with a translucent or transparent synthetic material layer, which is placed on top of the pattern in such a way as to protect the pattern against wear at least in certain areas. In this case, the composite material layer may form the surface of the final coated panel. However, a finishing layer may be provided on each layer of synthetic material, such as UV strengthening, electron beam strengthening or other polish layer, and may preferably comprise cured particles, such as ceramic particles of average particle size smaller than 200 μm. . In addition, the synthetic material layer may be located at the bottom instead of the upper part of the pattern, may be formed on the pattern or form part of the pattern, and may not necessarily be translucent or transparent.

In the synthetic material layer itself, a synthetic material comprising an amino resin such as melamine resin, PVC (polyvinyl chloride), polyethylene, polypropylene, polyurethane or polystyrene may be used.

Preferably, the method according to all aspects can be used to produce a coating panel, the substrates of which comprise wood based materials such as MDF or HDF. Such materials can easily be provided with a planar polished top surface, such that nonuniformity of the individual top surfaces will not affect the structure or relief formed on the top surface. In order to prevent this effect on the substrate, a base layer comprising a filler material may be used, and the nonuniformity of the upper surface of the substrate may be filled.

According to a particular aspect of the invention, when a layer of synthetic material, such as a PVC layer, is combined with a substrate of wood substrate, such as an MDF or HDF substrate, an adhesion layer is preferably provided between the composite material layer and the substrate. Such an adhesion layer can be used, for example, a sheet of material in which one side is provided with an amino resin such as melamine resin and the other side is provided with a separate synthetic material such as PVC. By using melamine resin, it can be easily attached to a substrate based on wood such as MDF or HDF. Also, as described above, the pattern may already be printed on this sheet of material.

According to all aspects of the present invention, preferably, the pattern is related to a printed pattern obtained by performing printing directly or indirectly on the substrate. For example, indirect printing can be obtained by printing one or more base layers already formed on the substrate. However, according to the present invention, the pattern printed on the sheet of flexible material to be provided or provided in whole or in part on the substrate is not excluded. Preferably, the pattern can be obtained through printing by an inkjet printer having one or more print head portions.

The steps mentioned in all aspects of the invention are carried out on a larger board and a final coated panel is formed, for example, using a pulverizing machine to separate such a wide board or to show an approximate area of the final coated panel. It can be molded into panels. In order to respond quickly to orders and to reject excess supply, it is desirable to form structures and / or patterns as late as possible in the manufacturing process. In this case, it is fed directly to panels having a similar or total area to that of the final coated panel. In this same case, each panel is subjected to an edge finish, such as a workpiece joining means or an edge portion of another shape. Of course, this does not exclude that an edge portion of this shape may be provided later during manufacturing. Providing a structural or embossed panel for each panel can prevent the risk of the structure disappearing, for example due to processing or lumber or other methods, for example the edge of a panel such as fillets less than 1 mm deep. It is associated with a relatively limited structure located at.

According to all aspects of the invention, preferably, the position of the relief or structure is relative to the final corner or corner portion of the coating panel, whether or not the corner can be obtained. Such a preferred embodiment can be carried out in the simplest manner at the point where the substrate already contains each final corner or corner point, but, for example, even if the substrate has not yet included the final corner or corner point, see, for example, Means are provided in which the arrangement is made in correspondence with the formation of the final corners or corner points and the proper positioning in correspondence with the final corners or corner points. For example, the present preferred embodiments can be used in symmetrical structures, for example, tile imitations with two or four lower edges or floor partial imitations, etc., and in a flexible manner the lower edges on both sides of the coating panel. The width of is formed the same or about the same.

Further, according to all aspects of the present invention, a structure can be preferably obtained corresponding to the above pattern.

In general, the embossments mentioned in all aspects of the present invention are limited in thickness and in practice relate to patterns of different glossiness. For example, sandblasting can be used as a material removal technique by the technique according to the fourth aspect, and matte areas can appear on the surface of the coating panel. It is also possible that the relief is preferably visible on the surface of the coating panel. However, in certain embodiments, although the relief is not noticeably noticeable on the surface of the coating panel, it is also possible for each relief to be included inside the top layer of the coating panel. Such an embodiment can be obtained where embossing is imparted to the pattern itself through the technique of the present invention, wherein the surface of the coating panel is made substantially or entirely flat. As already mentioned above, it is also possible to make this embossed depth effect visible and maintained on the surface of the coating panel. In addition, it is not prominently present on the surface of the coating panel, but does not exclude other visible effects.

To clearly illustrate the features of the present invention, examples are shown below, and the following drawings and preferred embodiments do not limit the features of the present invention.

Although FIG. 17 and FIG. 18 show various aspects, another modified example which shows the characteristic of the said 1st and 4th aspect is shown.

1 schematically shows some steps (S1-S5) in the method of manufacturing the coating panel 1. Each coating panel 1 comprises at least a substrate 2, for example an MDF or HDF base panel, on which the upper layer 3 is provided. For example, the upper layer 3 is composed of a plurality of material layers 4-7, in which the material layer 5, which appears as a pattern in step S2, appears in the form of a print 8 formed directly on the substrate. do.

In the previous step S1, one or more primary layers 4 are provided printed on the surface of the substrate 2 in the form of a pattern. These primary layers are attached to the material layer 5-8 to be applied in the form of a material layer 5 or a synthetic material layer 7 having a smooth surface and / or a uniform or semi-uniform background color and / or a later pattern. The purpose is to provide an undercoat.

FIG. 2 shows the results of step S1, showing that the non-uniform surface of the substrate 2 can be made flat or nearly flat through the one or more primary layers 4 described above.

For example, in step S1 one or more cylinders 9 can be used in a technical configuration. In step S1 of FIG. 1, it is clear that other technical configurations can be applied to form one or more primary layers 4. At the same time, although it is an important factor for determining the quality of the pattern, it is not necessary to form this primary layer 4 in the present invention. Instead of applying the primary layer 4 in liquid form, in forming the primary layer 4, a material such as a sheet of paper or the like, which may be provided in a dry or semi-dry form, on the substrate 2 may also be applied.

As described above, in the step S2 of FIG. 1, a pattern may be formed by directly printing 8 on the upper part of the substrate 2 or the upper part of the primary layer 4 already formed on the substrate 2. The pattern formed is related to the wood pattern formed in the longitudinal direction of the rectangular panel 1. In addition, this invention is not limited to such a pattern.

In this case, a printed pattern may be formed through the inkjet printer 10 having one or more head portions. For example, such a technique and apparatus can be known from the well-known EP 1 872 959 and the like, for example, in the above publication, the power supply portion of the inkjet print head portion is alternately formed side by side on the entire surface of the panel 1, This allows a multicolor print to be printed. It is clear that the step S2 of the present invention is not limited to this inkjet printing technique, and is not limited to the pattern printed directly on the substrate 2.

3 shows the result of the printing 8 formed directly on the substrate 2, in which case the primary layer 4 is formed above the substrate 2.

In step S3 of FIG. 1, an additional printing 6 is provided on top of the printed pattern. This relates to a print 6 comprising an antiswelling agent. This printing 6 is formed in a pattern that will determine the final structure or relief of the coated panel 1. Here, the pattern covers only a specific area of the printed pattern, preferably not extending to the entire surface of the final coated panel 1. In this case, the pattern is formed with a mask that provides the edges 11 of the panel 1 as well as the specific region 12 of the surface of the panel 1 containing the anti-expansion agent. The specific area 12 of the surface of the panel 1 here corresponds to the wood flowers or wood nerves present in the wood pattern and forms a recess in the final panel 1 similar to the shape of the hole. I will.

4 clearly shows again the position 11-12 of the printing 6 provided in the step S3.

In step S3, it is shown that the printing 6 determining the protrusion or structure is formed by a digital printing technique such as the inkjet printer 10. FIG. At this time, it is obvious that the printing 6 or the anti-swelling agent is not excluded from the fact that it can be applied in other ways.

In step S4 of FIG. 1, the synthetic material layer 7 is applied. This synthetic material layer 7 is preferably composed of a transparent or translucent material, and is preferably spread throughout the entire object panel 1. For example, a cylinder 9 can be used to apply this layer. However, this synthetic material layer 7 may be applied in other ways. Further, in the step S4, a plurality of synthetic material layers 7 may be applied on top of the synthetic material layer 7 already applied in the same manner or in another manner. Preferably, the wear resistant particles may be included in the synthetic material layer 7. For example, such particles may be included in the form of premixing or weaving into the synthetic material or the layer of synthetic material 7, or in other ways in such a way as to be scattered or laminated to the layer of synthetic material 7.

5 shows the result after step S4.

In step S5 of FIG. 1, relief is provided on the surface of the synthetic material layer 7 after step S4.

In FIG. 6 a coating panel 1 is obtained, in which the pattern of recesses 13 and protrusions 14 appear on the surface, which pattern is at least partly by printing 6 comprising an anti-expansion agent applied in step S3. It is decided. This structure is obtained in such a way that the synthetic material layer 7 is activated in step S5 and starts to spread. This activation can be achieved, for example, by heating the synthetic material layer 7 via radiation such as a hot-air oven 15, an infrared oven or UV or electron beams.

FIG. 6 shows where inflation is done only partially or not at all, in step S3, where an inflation or inflation inhibitor is applied. A recess 13 appears on the surface of the thickened synthetic material layer 7 at this position. In this way, for example, the shape of the fillet 16 can be obtained at the edge of the coating panel 1, and the recess 13 in the surface of the panel 1 in a form similar to the wood hole 17. Can be obtained. It is clear that the technique of the present invention may be applied only to the fillet 16 shape, to a shape similar to the wood hole 17, or to another shape.

6 shows that the formed recess 13 can have a structure including a rigid rounded portion 18.

7 shows that a sharp structure may also appear. Here, when the synthetic material layer 7 spreads, this synthetic material layer 7 comes to mind, and the forming mold 19 can be used to prevent this in the step S5. It is related to the technique of forming such a sharp fillet shape 16. In the preceding example, the forming mold 19 is a substantially planar pressing member. However, more than one pressurized cylinder or molding wheel may be used.

8 shows a state in which a sharp structure such as a sharp fillet 16 shape is obtained in another manner. Here, one or more of the above-described prints 6 for determining the structure are formed of a so-called deterioration layer, and the amount and concentration of the drug applied to the prints 6 may vary depending on the depth required at a particular location. In addition, this technique may or may not be combined with the technique described in FIG. 7.

Forming such a deterioration layer is advantageous in that the relief is at least partially determined through digital printing.

The manufacturing method of FIGS. 1 to 6 and the modifications of FIGS. 7 and 8 can be examples of the first and third aspects as well as the individual aspects mentioned in particular.

9 shows a preferred embodiment incorporating features of the first aspect. Here, the third aspect mentioned in the introduction can be applied to this purpose. Here, a structure is formed in the transmission element 20 via printing 6, in this embodiment a structure in the cylinder. The structure formed in this cylinder is applied to emboss the surface of the coating panel 1. Forming the print 6 on the transfer element 20 is performed inline at the same time as forming the recess 13 or emboss in the composite material layer 7 of the coating panel 1. To form the structure in the transfer element 20, digital techniques such as printing techniques via the inkjet printer 10 can be applied, for example a brightener or wax can be applied to the pattern of the cylinder. In addition, FIG. 9 shows that the structure of the cylinder is continuously replaced in such a way that the structure of the cylinder that has already been used is removed using, for example, the scrap device 21 or the like, and replaced with a new structure. The embodiment of FIG. 9 shows the features of the independent aspects mentioned in the introduction, ie the second and fifth independent aspects. It is also clear that the deterioration layer as described in FIG. 8 can also be applied to this embodiment.

10 shows another embodiment of the method, wherein a mask 22 is applied on top of the synthetic material layer 7, and then a material adhesion treatment is performed on the synthetic material layer 7. Here, the material adhesion treatment relates to coating the surface of the panel 1 with the liquid synthetic material 23. Here, the mask 22 is selected in such a way that the synthetic material 23 alone is attached where no mask 22 is provided.

11 shows the result after the mask 22, and shows a state where the portion to which the synthetic material 23 is not attached is removed. Embossing of the recess 13 and the protrusion 14 at the surface of the panel 1 can be obtained. This pattern can be determined by the mask 22 described above.

In addition, in the case of applying a printing mask, it is clear that there is an advantage in applying a so-called deterioration layer as described in FIG. 8.

FIG. 12 shows a variant of the method described in FIG. 9, which method comprises at least providing a layer of synthetic material 7 on the substrate 2 and embossing it using a mechanical pressing element 20 structured in this synthetic material. Providing a step. Here, the structure of the pressing element 20 takes place at the same time as providing the relief to the synthetic material. For example, the pressing element 20 is in relation to the roller. The difference between the embodiment of FIG. 12 and the embodiment of FIG. 9 is whether embossing is included in the composite material at this point before providing the structured composite material layer 7 in the panel 1. In other words, the synthetic material is already provided in the structured part of the pressing element 20, after which the formed synthetic material layer 7 is at least partially transferred to the panel 1.

FIG. 13 shows another variant in which the pressing element 20, in which the pressing belt and the pressing web are used instead of the roller, is conveyed toward the panel 1 via the roll 24. The pressurizing element 20 is of a type that can be provided to the feed roll 25. For example, this relates to foils such as synthetic foils, paper sheets or metal sheets such as aluminum foils. The dashed line 26 indicates that it can be operated using a circulation belt, at which time the scrap device 21 is preferably provided so that the already formed structured part can be removed. In this case, this endless belt can be used, for example, a metal belt.

Of course, similarly to the embodiment of FIG. 9, the arrangement of FIG. 13 can be applied when a synthetic material is applied to the panel prior to forming an emboss in the synthetic material layer 7. 13 shows that the synthetic material layer may be forced to dry through a specific drying station 27. This drying station 27 may be used, for example, a hot air oven, a UV heating device or an infrared heating device.

It is also possible to form the pressing element 20 in FIG. 13 on the opposite side 28 to obtain a similar effect. However, although this embodiment is not shown here, it is advantageous in that the risk of printing 6 being partially transferred over the panel 1 can be minimized.

The arrangement described in FIG. 13 corresponds to the arrangement shown in WO 2007/059667 publication, the difference from which is that instead of prior to the structured material web, an inline structured pressing element 20 or pressing web can be applied simultaneously. to be.

14 illustrates another embodiment that can minimize this risk. Here the substantially described process of FIG. 12 is applied, except that a foil 29 is used between the pressing elements 20, with the fact that these pressing elements are simultaneously structured in-line. This foil 29 is deformed by the structured pressing element 20, as a result of which a structure in which the structures of the recesses 13 and the protrusions 14 are arranged below the synthetic material layer 7 can be obtained.

The embodiment of FIGS. 13 and 14 is advantageous in that only the pressing element 20 and the foil 29 in the form of a web can individually contact the synthetic material of the composite material layer 7. This is particularly advantageous in that this synthetic material layer 7 may comprise wear resistant particles such as aluminum oxide. In this way, ie, other parts of the arrangement, such as roller 24, can be prevented from quickly wearing out.

FIG. 15 shows another embodiment similar to the embodiment of FIG. 12, but a print 6 having a structure determined or formed only in part can be transferred over the synthetic material layer 7. The technique of FIG. 15 can be used to form a mask 22 that may be applied as described in the fourth aspect in the introduction.

16 shows another embodiment, among other aspects, including the features of the fourth aspect of the invention. Here, the mask 22 which was initially provided to the synthetic material layer 7 is printed on the synthetic material layer 7 through a press treatment before the above-described material removal and / or material adhesion treatment is performed. In this case, this is related to the material removal treatment, that is, the brush treatment S6. Preferably, a drying treatment can be made to the synthetic material layer 7 prior to the material removal treatment, and as a result, the actual synthetic material layer 7 can be sufficiently resistant to this brush treatment S6. have. This drying treatment may be in a form similar to the drying station 27 of FIG. 13 although not shown here.

17 shows another embodiment, among other aspects, including the features of the fourth aspect. Here, a mask 22 is formed in a form in which the mask portion is prepared for a situation in which the synthetic material under the synthetic material layer is exposed to a material removal treatment in step S6, here, in a wide range. In this embodiment, the mask portion 30 may comprise a material which is impermeable or at least protects the UV radiation at the drying station 27, as a result of which the synthetic material layer 7 shown below The lower portion 31 of may have less solidification or not occur at all. The lower part 31 of this synthetic material layer 7 is removed in step S6 through the suction treatment shown, in this case with the mask 22. The mask 22 may be removed in a separate step, preferably the mask 22 may be removed before removing the unsolidified portion 31 of the synthetic material layer 7.

The mask 22 shown in the embodiment of FIG. 17 can appear through the possible digital printing 6, which can be obtained an embodiment of the first and fifth aspects of the present invention.

18 shows an embodiment in which a separate present mask 22 is used. In this case, the mask 22 consists essentially of translucent or transparent foil 29 and is provided to the mask portion 30 via printing 6. In this embodiment, as shown in Fig. 17, the mask in preparation for extensive exposure to the material removal treatment in this step S6, in this case the suction treatment, is located in the synthetic material portion 31 located below the mask portion 30. It is shown that the portion 30 is formed. This foil 29 is provided between the radiation source, in this case the drying station 27, and the layer of synthetic material 7 which is in the step prior to the material removal treatment, wherein the mask portion 30 is an optional screen, for example, The foil 29 is provided at a position to form the ultraviolet light emitted by the drying station. 18 shows one embodiment of how the mask 22 is removed from the synthetic material layer 7 in a separate step. In this case, the foil 31 is moved out of the synthetic material layer 7 before the unsolidified or less solidified portion 31 is exposed to the material removing process of step S6.

The mask portion 30 may be provided on either side of the foil 29, even on both sides of the foil 29. The embodiment shown above has the advantage that the mask portion 30 can be more simply removed from the synthetic material layer 7. If possible, a release layer comprising, for example, silicon and / or Teflon may be provided on the foil 29 surface which is in contact with the synthetic material layer 7.

The embodiments described in FIGS. 17 and 18 may represent one example of how a mask is formed inline at the same time as providing an embossment in the synthetic material. Here, another mask portion 31 may be applied at the same instant that relief is provided through the inkjet printer 10.

Although not shown, a number of masks 22 may be provided in succession and / or up and down. In the embodiment of FIG. 16, 17 or 18, another mask 22 before or after the previous mask 22 in the composite material layer 7 by the same pressing treatment or after the mask 22 has already been removed. Is printed. Through good selection of the various masks 22, the recesses 13 and / or the protrusions 14 may be formed in the form and / or other depths of the oblique wall.

The results of the methods according to the invention described in FIGS. 6, 7 and 9-18 can be finished with one or more finishing layers, such as a varnish layer.

The thicknesses of the material layers and the substrates described in FIGS. 2 to 7 and 9 to 18 are described only schematically and are not limited by the substrate. However, the thickness of the top layer is several tens of millimeters, and the thickness of the substrate may vary from 5 to 15 millimeters or more.

Rigid panels in accordance with all aspects of the present invention are made so that they can be rolled free. Rigid panels are advantageous in that two panels can be easily connected, such as floor panels, which can be drilled in the substrate to the shape of the connecting means, for example screws, dowels or mechanical joining means, where they can be joined together. . Such joining means and drilling techniques are known from publications such as WO 97/47834 or DE 20 2008 008 597 U1. Through the rigidity and bonding means of such a panel, the manufactured coating panel can be easily installed without applying an adhesive to the underlying layer.

The present invention is not limited to the above-described embodiment, and the method and panel of the present invention can be modified in various modifications without departing from the scope of the present invention.
